It can be bad caps in the power supply, bad backlights inverter circuits, bad lamps (black screen).
You will have to open it up and troubleshoot it.
If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed SONY and other monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Does an ONT Support Routing?


Query the ONT nameplate to determine whether an ONT supports routing. If "gateway HGU" is marked on an ONT nameplate, the ONT is of the gateway type and supports routing. If "bridging SFU" is marked on an ONT nameplate, the ONT is of the bridging type and does not support routing.
